Document Type and Number:
Japanese Patent JP2003529905
Kind Code:
A
Abstract:
The invention relates to a tubular discharge lamp (1) with a wall (4) which is transparent to UV-radiation. The tube (2) encloses a discharge space (5) having an internal diameter D. The discharge space (5) comprises a filling of mercury metal vapor in a concentration range of 0.4-2.5 mg/cm3. A reduction of both the diameter D from about 22 mm down to about 13.5 mm and the average mercury concentration from about 1.7 mg/cm3 down to about 0.8 mg/cm3 leads to an increase in the effective germicidal UV-output of the lamp (1) of about 35%.
